The association between sleep duration, obesity types and the risk of chronic diseases among occupational population in Shanghai City / 中国职业医学

Objective To investigate the relationship between sleep duration and obesity, and the risk of common chronic diseases in the occupational population in Shanghai City. Methods A total of 18 775 occupational individuals were selected as the study subjects using convenience sampling method in Shanghai City. Data on personal lifestyle behaviors and medical examination results were collected. The relationship between sleep duration and different types of obesity with dyslipidemia, hyperuricemia, hypertension, and hyperglycemia was analyzed. Results The incidence of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia among the study subjects was 24.9%, 16.2%, 11.5%, and 7.3%, respectively. The incidence of these four chronic diseases were higher in individuals with central obesity and suboptimal sleep compared to the control group (all P<0.01). Multivariate logistic regression analysis showed that suboptimal sleep combined with general obesity/overweight increased the risk of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia in the study subjects ［odds ratio (OR) were 2.40, 3.47, 3.30, and 2.79, respectively; all P<0.01］, after adjusting for age, gender, education level, marital status, occupation type, labor intensity, smoking, and drinking. Suboptimal sleep combined with central obesity also potentially increased the risk of these four chronic diseases (OR were 2.25, 3.09, 3.09, and 2.98, respectively; all P<0.01). Conclusion The incidence of common chronic diseases is relatively high in the occupational population in Shanghai City. Suboptimal sleep combined with different types of obesity increases the risk of common chronic diseases.

Clinical analysis of combined direct and indirect extracranial-intracranial bypass in 25 adult patients with Moyamoya disease / 中国神经精神疾病杂志

[Abstrict]Objective To explore the key points and clinical value of combined direct and indirect extracranial-in?tracranial (EC-IC) bypass in patients with adult moyamoya disease. Methods Retrospective analysis of combined revas?cularization surgery in 25 adult patients with moyamoya disease. The frontal branch and parietal branch of the superficial temporal artery (STA) were dissected. Combined revascularization surgery consisted of direct (anastomosis between the su?perficial temporal artery and cortical branch of the middle cerebral artery) and indirect (encephalodurogaleosynan-giosis EDAS) surgeries. Clinical status was evaluated using the modified Rankin Scale and NIHSS score at 1 day before, 1 week and 3 months after surgery. Results Thirty lateralities were successfully performed on 25 patients. Postoperative angiogra?phy or CTA and cranial computer tomography perfusion imaging(CTP) were conducted to examine the patency of the di?rect anastomosis and cerebral blood flow in 23 patientswithin 1 weeks after surgery . The results showed that the anasto?motic vascular patency was excellent and the cerebral blood flow increased in parallel to the relief of the patients’s isch?emic symptoms. The median mRS scores were 3 (1,3) before surgery, 2 (1,3) 1 week and 1 (0,3) 1 month after surgery.The median mRS scores were significantly improved (Z=15.14, P<0.01). The median NIHSS scores was 5 (4,8) preopera?tively and 4(2,7) postoperation 1 week and 3(1,4) 3 months. The median NIHSS scores were also significantly improved (Z=11.36, P<0.01). Unfortunately, two patients had complication and left hemiparesis. One patient complicated with con?tralateral hemisphere infarction and the another one complicated with ipsilateral hemispheric hemorrhage after operation. Conclusions Combined revascularization surgery may result in satisfying improvement in clinical, angiographic, and he?modynamic states and prevention of recurrent stroke. The stabilized hemodynamic is the key point in peroperative period for moyamoya patients.

The role of Kupffer cells on the postburn production of TNFalpha, IL-1beta and IL-6 in severely scalded rats / 中华烧伤杂志

<p><b>OBJECTIVE</b>To observe the role of Kupffer cells in the postburn production of TNFalpha, IL-1beta and IL-6 in severely scalded rats.</p><p><b>METHODS</b>(1) The production of TNFalpha, IL-1beta and IL-6 from rat Kupffer cells stimulated by burn serum was observed. (2) The postburn change in the expression of cytokine mRNA from rat Kupffer cells was monitored. (3) The change in the plasma cytokine contents in scalded rats was determined after the application of gadolinium chloride, a specific inhibitor of Kupffer cells.</p><p><b>RESULTS</b>Kupffer cells could be stimulated by burn serum to release cytokines TNFalpha, IL-1beta and IL-6. The mRNA expression of TNFalpha, IL-1beta and IL-6 from rat Kupffer cells increased significantly after injury. But the postburn plasma levels of TNFalpha, IL-1beta and IL-6 decreased obviously to 34.71%, 36.99% and 33.7% of those in scalding group, respectively, after the Kupffer cell activity was inhibited.</p><p><b>CONCLUSION</b>The plasma cytokines, i.e. TNFalpha, IL-1beta and IL-6, were primarily produced from Kupffer cells after injury in scalded rats, initiated by TNFalpha, IL-1beta and IL-6 mRNA transcription.</p>

Effect of burn injury on relative anaplerosis and gluconeogenesis in rats by 13C magnetic resonance spectrum / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To introduce a safe and specific approach of (13)C magnetic resonance spectrum ((13)C MRS) spectroscopy and investigate the alterations in hepatic anabolism.</p><p><b>METHODS</b>Relative anaplerotic, pyruvate recycling and gluconeogenic fluxes were measured by (13)C MRS isotopomer analysis of blood glucose from rats with 40% body surface area burn injury, and from rats exposed to sham injury. A short chain fatty acid, [U (13)C] propionate which was avidly extracted by the liver, was infused intravenously to deliver (13)C into the citric acid cycle. Proton-decoupled (13)C MRS of deproteinized plasma or extracts of the freeze-clamped liver were used to determine the distribution of (13)C in blood or hepatic glucose.</p><p><b>RESULTS</b>There was no difference in the multiplets detected in the glucose carbon-2 anomer from blood or liver after 45 or 60 minutes of the infusion of the propionate, indicating that steady-state isotopic conditions were achieved. Gluconeogenesis relative to citric acid cycle flux was not altered by burn injury; in both sham and burn groups the rate of glucose production was about equal to flux through citrate synthase. In the sham group of animals, the rate of entry of carbon skeletons into the citric acid cycle was about 4 times than that in the burn group. Similarly, flux through pyruvate kinase (again relative to citrate synthase) was significantly increased after the burn injury.</p><p><b>CONCLUSIONS</b>Since results from analysis of the blood glucose are the same as that of the hepatic glucose, (13)C distribution in the glucose and hepatic metabolism can be assessed based on the (13)C MRS analysis of the blood glucose.</p>
